Npmlog like Logger for Browser

This logger simulate the basic npmlog behaviour in browser.

Feature

1. Support import with TypeScript. (typing file index.d.ts)

2. Support Angular2 & SystemJS. (demo project git repository)

3. Support show real line number in browser console.

   What I really get frustrated by is that I cannot wrap console.* and preserve line numbers

   We enabled this in Chrome DevTools via blackboxing a bit ago.

4. Certainly it can run under nodejs. (Just for test & fun. example here)

Basic Usage

var log = require('brolog')

// additional stuff ---------------------------+
// message ----------+                         |
// prefix ----+      |                         |
// level -+   |      |                         |
//        v   v      v                         v
    log.info('fyi', 'I have a kitty cat: %j', myKittyCat)

log.level()

• {String}

The level to display logs at. Any logs at or above this level will be displayed. The special level silent will prevent anything from being displayed ever.

log.log(level, prefix, message, ...)

• level {String} The level to emit the message at
• prefix {String} A string prefix. Set to "" to skip.
• message... Arguments to util.format

Emit a log message at the specified level.

log[level](prefix, message, ...)

For example,

• log.silly(prefix, message, ...)
• log.verbose(prefix, message, ...)
• log.info(prefix, message, ...)
• log.warn(prefix, message, ...)
• log.error(prefix, message, ...)

Like log.log(level, prefix, message, ...). In this way, each level is given a shorthand, so you can do log.info(prefix, message).
